Manipulation of 3D Models Using Hand Gesture

This program allows user to manipulation 3D models (.obj format) with their hands. The project support both the OAK-D and OAK-D-LITE.


Install dependencies

On an Intel-based macOS or Linux machine, run the following command in the terminal:

git clone
cd vision_ui
python3 -m pip install -r requirements.txt

For Linux only, make sure your OAK-D device is not plugged in and then run the following:

echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="03e7", MODE="0666"' | sudo tee /etc/udev/rules.d/80-movidius.rules
sudo udevadm control --reload-rules && sudo udevadm trigger

To run

  1. Make sure the OAK-D/OAK-D-Lite device is plug into the computer.
  2. In the terminal, run


AI Model description

The ai_models folder includes two Intel Myriad X optimized models:

  1. palm_detection_sh4.blob: This is the palm detection model
  2. hand_landmark_sh4.blob: This is the model to detect the hand landmarks using the palm detection model
